“The happiness and unhappiness of the rational, social animal depends not on what he feels but on what he does; just as his virtue and vice consist not in feeling but in doing.”

“Happiness and unhappiness are in the heart and spirit of each one of us: If you feel unhappy, then place yourself above that and act so that your happiness does not get to be dependent on anything.”

“It is necessary to the happiness of man that he be mentally faithful to himself. Infidelity does not consist in believing, or in disbelieving, it consists in professing to believe what he does not believe.”

For what a man has he may be dependent upon others; what he is rests with him alone.”
